CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rightsapplication number 2018/0179, filed Jan. 16, 2018, which is hereinincorporated by reference.

Latin name of the genus and species:

The Latin name of the genus and species of the novel variety disclosedherein is Vanda spp. Jones ex R. Br.

Variety denomination: The inventive variety of Vanda disclosed hereinhas been given the variety denomination ‘SPCDW1712’.

BACKGROUND OF THE INVENTION

Parentage: The new Vanda plant, ‘SPCDW1712’, is the result of a plannedbreeding program. ‘SPCDW1712’ originated as a seedling from thecontrolled pollination of Vanda ‘S76’ (not patented), the seed parent,with Vanda ‘A274’ (not patented), the pollen parent. Both parents weredeveloped by, and are owned by, the inventor and were never commerciallyreleased. The crossing was made by the inventor in his researchgreenhouse in Bangphra, Thailand in April of 1994.

The new variety was first selected in September of 1998, in a researchgreenhouse in Bangphra, Thailand belonging to the inventor. Afteridentifying the new variety as a potentially interesting selection, theinventor continued confidential testing and propagation of ‘SPCDW1712’,assessing stability of the unique characteristics of this variety.

Asexual Reproduction: Asexual September of 2011 at a commerciallaboratory belonging to the inventor in Bangphra, Thailand. Access toall plants was restricted, as plants were kept in a greenhouse not opento the public, and tissue culture plantlets were in a laboratorybelonging to the inventor, and not accessible to the public. Through sixsubsequent generations, the unique features of this cultivar have provento be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘SPCDW1712’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype. The followingtraits have been repeatedly observed and are determined to be the uniquecharacteristics of ‘SPCDW1712’. These characteristics in combinationdistinguish ‘SPCDW1712’ as a new and distinct Vanda cultivar:

-   -   1. Vanda ‘SPCDW1712’ exhibits a compact growth habit, with        improved plant vigor and a freely flowering bloom habit; and    -   2. Vanda ‘SPCDW1712’ exhibits an abundance of large flowers,        proportionately arranged on an inflorescence which is carried        well above the foliage; and    -   3. Vanda ‘SPCDW1712’ exhibits white flowers with dark violet,        conspicuous reticulate veining; and    -   4. Vanda ‘SPCDW1712’ exhibits a labellum with a very dark violet        central lobe, and light violet lateral lobes.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in August of 2018describe averages from a sample set of six specimens of six year-old‘SPCDW1712’ plants grown in a greenhouse in Honselersdijk, theNetherlands. Temperatures were approximately 23 degrees Celsius duringthe day and 19 degrees Celsius at night. No photoperiodic or chemicaltreatments were given to the plants. No artificial light was given tothe plants.

Those skilled in the art will appreciate that certain characteristicswill vary with older or, conversely, with younger plants. ‘SPCDW1712’has not been observed under all possible environmental conditions. Wheredimensions, sizes, colors and other characteristics are given, it is tobe understood that such characteristics are approximations or averagesset forth as accurately as practicable. The phenotype of the variety maydiffer from the descriptions set forth herein with variations inenvironmental, climatic and cultural conditions. Color notations arebased on The Royal Horticultural Society Colour Chart, The RoyalHorticultural Society, London, 2015 (sixth edition).
